Comments to classification. As suggested by the absence of paragenae, shape of the mouth parts (deeply bilobed labrum, falcate mandibles with acute tips and retinaculum, long and slender maxillary palpomeres) and metacoxal lines on abdominal ventrite I running from inner end of metacoxa posterolaterad to posterior margin of the ventrite, the species belongs to the genus Mystrops ( Cryptoraea Reitter, 1873 was synonymised with Mystrops by Kංඋൾඃ- ඍඌHඎK (2008)). It is a species apparently closely related to M. bourgeoisi , from which it differs in fluently convex lateral margins of pronotum (concave besides posterior angles in M. bourgeoisi ) and orange antennae, legs and pygidium (both appendages and pygidium dark, blackbrown in M. bourgeoisi ). The new combination Mystrops rufidens ( Reitter, 1873) was published by KංඋൾඃඍඌHඎK & Cඈඎඍඎඋංൾඋ (2010) in the diagnosis of Mystrops atrata Kirejtshuk & Couturier, 2010 and in the review of the classification of Mystrops in the same paper, in both cases without any comments on the original combination or formal publication of the proposed lectotype designation.
